Puppy Growth Calculator โ Is My Puppy Growing Normally?
It is natural to worry about whether your puppy is growing as it should. Our calculator compares your puppy's current weight with the expected weight based on age and expected adult weight, so you can quickly see if your puppy is on track.
How do puppies grow?
Puppies grow fastest in the first 6 months of their lives. A puppy typically reaches about 50% of its adult weight by around 4-5 months of age. Small breeds are often fully grown by 10-12 months, while large breeds can continue growing up to 18-24 months. Growth is not perfectly linear, but our calculator provides a good estimate.
What does the deviation mean?
A deviation of +/- 10% is completely normal and nothing to worry about. If the deviation is greater than 20%, it may be a good idea to talk to your vet. An underweight puppy may need more food or there could be health-related causes. An overweight puppy may need more exercise or an adjusted diet.
Factors affecting growth
Several factors affect puppy growth: breed, genetics, diet, exercise and health status. Puppies from large litters may be smaller at birth but often catch up. It is important to feed the puppy quality food designed for puppies, as they have different nutritional needs than adult dogs.
When should I contact the vet?
Contact your vet if your puppy consistently deviates more than 20% from the expected weight, suddenly stops growing, loses weight, or shows signs of discomfort. Regular weigh-ins and vet visits ensure your puppy develops healthily.
